@mathiasbynens FTW!
Much better.

I tried to make it work using cp before but couldn't get it working for some strange reason. I forget the original issue I ran into.


Feel free to backport these changes into your original gist if you like! It’s still your script :) I’ll update my blog post accordingly.


Great script guys! Thanks!


Be sure to check out Appify UI also:


I used this today to on a .sh script of mine. When launching the app it states: "You can't open the application...because PowerPC applications are no longer supported. I'm running Mountain Lion. My .sh script runs fine natively, it is small and just uses a couple curl lines to download some tar.gz files. Any ideas?


OS X 10.8.5:
You can’t open the application “My” because it is not supported on this type of Mac


same error message as PacoH for me, unfortunately!


Same problem, the end result seems to be a PowerPC app. I guess it's just a matter of changing one of the triggers (?) but which one… If somebody has an idea, it would be great!


I got around that PowerPC issue by ensuring that #!/bin/bash was at the top of my script ;)


Running on mac OSX 10.10.2
I had trouble with the powerpc error.
I had to add the #!/bin/bash line to my shell script as noted above.
I had to modify my plist to be correct as noted previously.
In particular I had to change CFBundleSignature from ???? to a 4 character string.
It then worked for me.


Can someone post a simple .plist file that does the following...

1) Allows App to be a drag + drop target.

2) Passes dropped files into script $* to allow files to be dropped on App.

I'll also look around + if I find a good example, post it here.



I made it to work on OS X 10.10 by adding file $ containing <plist><dict></dict></plist>


Neat idea. However, what directory does the script run in so that I can use relative paths?


-bash: /Users/--------/Desktop/ Permission denied


chmod +x /Users/--------/Desktop/


OS X 10.10.5: You can’t open the application “My” because it is not supported on this type of Mac

adding the Info.plist with next content didn't help:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "">
<plist version="1.0">

Any ideas how to make it work on Yosemite?


+1 any idea on how to make this work on OS X 10.10 or higher?
I'm not familiar with the OS X plists internals... could somebody please post a working example?


I worked for me after I ran this: /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -f

It started working (OS X 10.11.2) when I changed #!/bin/bash to #!/usr/bin/env bash at the first line of my .sh script


use this awesome utility for creating .app package no error related to power pc

Hey guys,

Just put the correct shebang on your .sh file and everything will work fine. For instance: #!/bin/bash.
Also, don't forget to add execution permission for your .sh file: chmod +x
With these steps, there is no PowerPC error :)


my script looks like this

cd /Users/dr/Documents/Leo/leo-editor

and i added the execution permission for my .sh file.

The applified application dies immediately and I see the following entry in the console log:

15/08/16 12:52:55,087[1]: ([12195]) Service exited with abnormal code: 1

os is 10.11.5
